Bulking snag

I'm new to the forums so please don't hate me if I get some of the procedures wrong. I work at a hospital full time and have a hard time getting meals in like clockwork. I went from 145lbs to my current of 165lbs in a month. I haven't gain anything since and need some advice. I have a cow's milk/lactose problem so some of the diet stuff I can't work with. But here's my stats...

wt: 165lbs
ht: 6'1
age: 26
BF%: no clue, I'm a skinny bastard

My diet has consisted of:

(morning)

Homemade weight gainer shake:
1/3c raw oatmeal
4tbsp flaxseed oil
1/3c natural peanut butter
1 banana
2scoops whey isolate powder(i know it's milk based but it hasn't given me more than a mild case of hives which clears up in an hour)
16oz soy milk (chocolate flavor)
1 tbsp natural cocoa syrup

I also pair this with my GNC vitapaks since I'm too F'ing full to eat anything after that.

before lunch snack:
Met-rx super cookie crunch bar


lunch:

I'm a newbie to bulking, suggestions or an overhaul would be great. I'm on a fixed budget with a family to support. I'm not really looking for super huge, but I'd like to be 190 to 200lbs.

Thanks in advance
